Clake has a couple of options for reducing clutch effort on hydraulic clutches. The simplest and cheapest is the Clake One Light Clutch. It uses an internal cam to reduce the effort instead of just changing the pivot point, so you still get the full clutch travel and you wouldn't have to mess with exact freeplay/engagement adjustments.
But the cam system has its own drawbacks. When the cam is providing the most assistance (when the clutch is pulled in near the bar), there is correspondingly less force pulling the clutch lever back out when you release the lever. I found the lever would tend to get "hung up" on the cam when fully pulled in and wouldn't smoothly release. I ended up adding an external coil spring fastened between the lever and the barkbuster to pull the lever back out. For the price, it really should have a small return spring built in.
